java 获取当前年份 月份 日期

一、使用Calendar

Calendar cal = Calendar.getInstance();

int day = cal.get(Calendar.DATE);

int month = cal.get(Calendar.MONTH) + 1;

int year = cal.get(Calendar.YEAR);

int dow = cal.get(Calendar.DAY_OF_WEEK);

int dom = cal.get(Calendar.DAY_OF_MONTH);

int doy = cal.get(Calendar.DAY_OF_YEAR);

System.out.println("Current Date: " + cal.getTime());

System.out.println("Day: " + day);

System.out.println("Month: " + month);

System.out.println("Year: " + year);

System.out.println("Day of Week: " + dow);

System.out.println("Day of Month: " + dom);

System.out.println("Day of Year: " + doy);

二、使用Date

Date d2 = new Date();

int year = d2.getYear() + 1900;

int month = d2.getMonth() + 1;

int date = d2.getDate();

int hour = d2.getHours();

int minute = d2.getMinutes();

int second = d2.getSeconds();

int day = d2.getDay();
